Uncertainty cost analysis of heterogeneous wireless network based on loan repayment approach

Mobile Network Operators (MNO) are recently fronting the extreme penetration of high data rate demands, rapidly expansion in smart mobile devices and round-delay trip time, which decoupling the service provider investments with mobile traffic flow. Therefore, an urgent need to deployment of such capable business approaches who provide the ultimate solution in sense to reduce the entire wireless network cost and to split the uncertain expenditures with well-organized manners. In this case, we consider the foremost issues of the wireless network for uncertainty cost analysis that comprising on different types of parameters such as site leasing, radio network controller, backhauling, integrating, electricity bills, interest rate, operation & maintenance, base station equipment's and implementation charges. We calculate the total cost of ownership (TCO), operator investments and recurring expenses using the well-known loan repayment method. Finally, comparing the indoor coverage-capacity experimental results among each site structure, we are able to conclude that femto base station and distributed antenna system (DAS) using as the alternate have significant impact on operator margins regarding their low cost in our proposed scenario.
